Amorphous Alloy Three-Phase Oil Immersed Power Transformer is widely used in urban and rural power grid construction and renovation projects.

Product features:

1. Energy saving and consumption reduction: SH(B) 15-M amorphous alloy core oil immersed transformer compared with S11 transformer of the same capacity, the no-load loss decreases by about 60%, and the no-load current decreases by about 60%.

2. Enhanced ability to resist sudden short circuit: copper foil winding is adopted for low voltage, so that the electric field of the transformer is evenly distributed.The low voltage inner frame is made of formed cardboard tube, and the high voltage outer half stack is made of a layer by a layer of glass adhesive tape without weft. The laminated wood pad is used to strengthen the mechanical strength of the transformer.The transformer uses vacuum oil filling method to completely eliminate the bubbles in the coil, thus improving the transformer's ability to withstand sudden short circuit as a whole. 

3. The transformer connection group adopts Dyn11 to reduce the influence of harmonic on the power grid and improve the power supply quality. 

4. Tank rim uses stainless steel bolts, appearance is beautiful .

5. The oil tank adopts fully sealed oil tank to isolate transformer oil from air and slow down the aging of transformer oil.


Range of application:

The product is widely used in urban and rural power grid construction and renovation projects.The transformer can replace the transformer of silicon steel core and is widely used in outdoor distribution system.A large number of the product into the network operation can achieve good energy saving effect and reduce the air pollution.This product is especially suitable for the areas with insufficient electric power, large load fluctuation and difficulty in daily maintenance.Because the transformer adopts a fully sealed structure to avoid the contact between transformer oil and air, it can operate in the humid environment and is the ideal distribution equipment in the vast urban and rural distribution network.
